I know the world is clamoring for GSP Diaz right now, and thats cool. I dont mind seeing that fight. Kinda seems like Diaz should have to win at least ONE back in the big league before he gets a shot, but it wouldnt be THAT absurd if he did.
Maybe AFTER GSP and him fight, BJ fights Diaz. Whether he is champ or not. If Diaz loses to GSP, then him and Penn fight just because it would be a great fight. And if Diaz beats GSP then hey you know the UFC is all about giving Penn a title shot.
I personally think BJ would destroy Diaz, which is why I wouldnt want to see that fight till after Diaz fights GSP.
